Answer:
X=7
Step-by-step explanation:
HJ + JK = HK
3(X + 2) +(3X - 4) = 44
3X + 6 + 3X - 4 = 44
6X + 2 = 44
6X = 42
X = 7
Answer:
10x + 15y = 450
Step-by-step explanation:
A store sells bracelets for $10 and rings for $15.
Sold 30 items.
They counted the money they made $450.
x = bracelets
y = rings
10x + 15y = 450
Answer: s + 30 ≥ 50; s ≥ 20
Step-by-step explanation:
let s be the amount you have yet to spend in order to reach $50 or more
you already have $30.
This means you need to spend at least $20 more ($50 - $30 = $20)
S can be greater than or equal to $20 because your total will be 50 or more, therefore qualifying for the discount.
